How high sugar can damage eyes |Diabetes:Blindness and blurry vision -Dr. Anantharaman Ramakrishnan

How does glucose damage the eye? What is the link between glucose and eye. One important thing to note is at the back of the eye there is retina. Retina is a sensor and it senses the light that comes in the eye and that is how we perceive the world around us. These retinal blood vessels can sometimes get clogged because of the high blood glucose. The high blood glucose that is present in the blood can affect the blood vessel walls and once the blood vessel walls gets occluded, what happens is new blood vessel s have to grow and retina has one of the highest oxygen requirement s in the body and because of this oxygen requirement new blood vessel s starts forming and there is partial ischemia of the blood vessels and due to these new blood vessel s that are forming, what happens is the new blood vessels leak. When the new blood vessels leak, you can get haemorrhage into the retina or you can get a collection of fluid behind the macula or the central part of the eye where the vision is perceived. Trough these two mechanisms, patients with diabetes where he blood glucose is high. That is how the glucose impacts on the eye and reduces the vision.
